what is fremite/is it useful?

Answer 1

Fremitus is a palpable vibration on the human body. In common medical usage, it usually refers to (tactile) vocal fremitus, although there are several other types.
Bronchial Fremitus

See rhonchal fremitus below.
Hepatic Fremitus

Hepatic fremitus is a vibration felt over the patient's liver. It is thought to be caused by a severely inflamed and necrotic liver rubbing up against the peritoneum. The name 'Monash sign' has been suggested for this clinical sign, after the Monash Medical Centre in Melbourne, Australia (Nagappan et al, 2001).
Hydatid Fremitus

Hydatid fremitus is a vibratory sensation felt on palpating a hydatid cyst.
Pectoral Fremitus

See vocal fremitus below.
Pericardial Fremitus

Pericardial fremitus is a vibration felt on the chest wall due to the friction of the surfaces of the pericardium over each other. See pericardial friction rub for the auditory analog of this sign.
Pleural Fremitus

Pleural fremitus is a palpable vibration of the wall of the thorax caused by friction between the parietal and visceral pleura of the lungs. See pleural friction rub for the auditory analog of this sign.
Rhonchal Fremitus

Rhonchal fremitus, also known as bronchial fremitus, is a palpable vibration produced during breathing caused by partial airway obstruction. The obstruction can be due to mucus or other secretions in the airway, bronchial hyperreactivity, or tumors. See rhonchus (rhonchi) for the auditory analog of this sign.
Subjective Fremitus

Subjective fremitus is a vibration felt by the patient on humming with the mouth closed.
Tactile Fremitus

See vocal fremitus below.
Tussive Fremitus

Tussive fremitus is a vibration felt on the chest when the patient coughs.
Vocal Fremitus

Vocal Fremitus, also called pectoral fremitus, or tactile vocal fremitus, is a vibration felt on the patient's chest during low frequency vocalization. Commonly, the patient is asked to repeat the phrase 'ninety-nine' while the examiner attemps to detect vibrations on the chest wall.

Vocal fremitus is normally more intense in the right second intercostal space, as well as in the interscapular region, as these areas are closest to the bronchial bifurcation.

Answer 3

I agree with you that the sent is probably finite, but that might be hard to prove. So far, my best candidate for such a "largest useless number" is 2835, but I'll keep refining my searches, which is pretty time consuming even for a computer. I suspect it's a 4 digit number. Maybe Quadrillator can help me in debunking this number 2835, by showing how it's an useful one? Edit: Vikram P, on the nose. Yes, that's right, it's an awful lot of combinations to have to try out. Regardless, it has to be taken on faith that if every number from A to B is proven to be an useful one, regardless of the size of the difference B - A, there isn't any useless number higher than B. And I don't think I'm going to try proving any upper limit. But anyway, I'm still doing some computer searches right now. Understand that once any number is found to be "useful", that can't be undone. So it's a matter of compiling huge lists of such "useful numbers" and looking for gaps which can be proven to be useless for the given range of search. But this is not a proof of any upper limit. Edit 2: Vikram P, 2835 is the largest I've found SO FAR. I'm trying to see if I can find another gap higher up. Sure taking forever. Computers are so slow. Edit 3: Latest results: Every number from 2836 to 20000 has proven to be "useful". Maybe I'll run a longer search overnight, but I've got work to do on this computer. Edit 4: I see the combination making 2835 useful, so I'll have to see why my search somehow missed this one, even after catching all the others. Edit 5: Oh sheesh, I see now the SLIGHT programming mistake. I'll redo everything and see if Quadrillator's candidate is the one. Give me some time. It's amazing how close you can come to correct results and still not quite get it because of things like this. Edit 6: Okay, it's confirmed. Quadrillator's suggested candidate, 1522, is "probably" the largest useless number. All the numbers from 1523 to 30000 are useful numbers. This took a few hours computing time. Edit 7: For the different permutations of squares and cubes, for n terms, let m = 0 to 2^n - 1 in binary form. Then compute ∑ (k = 1 to n) (x + k - 1)^(2 + [kth binary digit of m]), for all m, and for x = 1 and up. My original mistake was that it left out exactly one of the possible permutations in certain circumstances, having to do with array operations. That gives you an idea of how redundant the useful numbers can be above a certain amount, right around 3000 or so.
